This refers to a spinning machine that can obtain a fiber cross section and shape of a pattern.

  A fiber manufactured by such a melt composite spinning machine is called a composite yarn (composite fiber). The composite yarn has a cross-sectional shape such as a core-sheath type, a side-by-side type, and a sea-island type by composite spinning of different fiber polymer raw materials.

  The multiple composite yarn (multiple composite fiber) described above or described below is the concept of a composite yarn (composite fiber) that normally contains two types of polymer materials in one fiber fiber. In contrast, it refers to fiber yarns that contain various polymer materials in various forms (core-sheath type, split type, sea-island type, etc.). Mixed yarns (mixed fibers) are polymer materials, consistency, and physical properties. It is defined as a material in which various polymer fiber materials having different cross-sections and the like are mixed in one yarn.

First Embodiment FIG. 1 is a view exemplarily showing a multiple fiber spinning device 100 according to a first embodiment of the present invention.

  As shown in FIG. 1, the multi-fiber spinning device 100 according to the first embodiment of the present invention includes an extruding unit 110: 111, 112, 113, a spin block unit 120, a spinning nozzle unit 130, an electric heater unit 140, and a cooling device unit. 150 and a height adjusting unit 160.

  First, the extruding unit 110 according to the first embodiment of the present invention serves to melt and extrude a polymer raw material charged in a hopper (not shown) located at an upper portion and transfer it. For example, three extruders 111, 112, and 113 are arranged at other positions, respectively, and after the polymer raw material is charged and melted and extruded, it is transferred to the spin block unit 120 described later.

  The spin block unit 120 of the present invention includes a gear pump unit 120A: 121, 122, 123, 124, 125, 126 and a flow channel unit 120B: 127, 128, 129, 121a, 122a, 123a, 124a, 125a, 126a. . The reference numerals 120A and 120B are not shown in FIG.

  First, the gear pump unit 120A will be described. The gear pump unit 120A of the present invention includes a plurality of gear pumps 121, 122, 123, 124, 125, and 126, and is formed on the inner right side of the spin block unit 120 among the plurality of gear pumps. The gear pumps 121 and 122 can receive the polymer raw material supplied from the extruder 111 formed on the outer right side of the spin block unit 120 through the corresponding channel tube 127.

  On the other hand, the gear pumps 123 and 124 formed on the inner upper side of the spin block unit 120 of the present invention are supplied with the polymer raw material supplied from the extruder 112 formed on the outer upper side of the spin block unit 120. The gear pumps 125 and 126 formed on the inner left side of the spin block unit 120 can receive the polymer raw material supplied from the extruder 113 formed on the outer left side of the spin block unit 120. Can be received through.

  As described above, each gear pump is connected to each flow pipe and the extruder to receive the molten and extruded polymer raw material, and is also connected to a gear motor not shown in FIG. Structure. With such a connection structure, the gear pump unit 120A of the present invention serves to discharge the polymer raw material melted and extruded by the extruders 111, 112, and 113 by the gear motor at the same or different discharge amounts. To come. At this time, discharging different discharge amounts means that the fibers are discharged with different fiber thicknesses.

  Thus, in the first embodiment, in the existing melt spinning machine (or compound spinning machine), only one gear pump can be provided for each extruder with respect to one extruder or two extruders. In order to improve the limit, three or more extruders 111, 112, 113 are provided, and two gear pumps are included in each of the extruders 111, 112, 113.

  However, it is not necessarily limited to the configuration of two gear pumps for each of the extruders 111, 112, and 113, and more extruders and gear pumps can be provided although structurally unlikely. Needless to say.

  Further, for the gear pump unit 120A for discharging the molten polymer raw material with different discharge amounts, a control device for adjusting a specific discharge amount for each gear pump is further provided inside or outside the spin block unit 120. Needless to say, you can.

  Next, the flow path pipe portion 120B of the present invention includes a plurality of flow path pipes 127, 128, 129, 121a, 122a, 123a, 124a, 125a, and 126a. At this time, each flow pipe is individually formed for each gear pump.

  That is, in the flow channel section 120B, the flow channel tube denoted by reference numeral 121a is formed between the U1 gear pump 121 and the N1 spinning nozzle 131 described later, and the flow channel tube denoted by reference numeral 122a is coupled to the U2 gear pump 122. It is formed between an N2 spinning nozzle 132, which will be described later, and a flow path pipe denoted by reference numeral 123a is formed between a U3 gear pump 123 and an N2 spinning nozzle 132, and a flow path pipe denoted by reference numeral 124a is a U4 gear pump 124. N1 spinning nozzles 131 are formed.

  Further, a flow path pipe denoted by reference numeral 125a is formed between the U5 gear pump 125 and the N1 spinning nozzle 131, and a flow path pipe denoted by reference numeral 126a is formed between the U6 gear pump 126 and the N2 spinning nozzle 132. .

  As described above, the channel pipe portion 120B of the present invention can be formed one by one for each of the corresponding configurations between the multiple gear pumps 120A and the spinning nozzle portion 130 described later. Alternatively, in order to improve the structure in which only one or two channel pipes are formed between a gear pump consisting of only two and one spinning nozzle, the portion through which the channel pipes pass is made into a laminated structure. This is because a plurality of flow channel tubes can be formed one by one between the gear pump and the spinning nozzle without making contact with each other.

  In the first laminated structure, for example, in the first laminated structure, a semicircular long flow pipe that is a part of the flow pipe is formed, and the remaining semicircular long flow pipe is formed in the second laminated structure of the next stage. Thus, the flow path pipes can be formed in a long shape between the gear pump and the spinning nozzle without contacting each other.

  Next, the spinning nozzle unit 130 of the present invention includes a plurality of spinning nozzles, for example, two spinning nozzles 131 and 132. For each spinning nozzle 131 and 132, one gear pump and a corresponding flow channel pipe are provided for each extruder. Connected through. As a result, the illustrated spinning nozzles 131 and 132 are connected to the three flow channel pipes, respectively, and can receive various types of molten polymer polymers flowing in from the gear pump unit 120A. It plays the role of spinning at the same time.

  Such a spinning nozzle portion 130 of the present invention is preferably formed in two in terms of structure, but is not necessarily limited to this, and a gear pump and a channel pipe corresponding to the gear pump are further formed for each extruder. If you do, you can be more prepared accordingly.

  Further, a control device (not shown) for controlling the spinning nozzle unit 130 along with the control of the gear pump unit 120 </ b> A in order to selectively spin various polymer resins by the spinning nozzle unit 130 is a spin block unit 120. Can be further provided inside or outside. The said control apparatus can further control the electric heater part 140 etc. which are mentioned later. On the other hand, the fiber yarn 170 containing a large number of polymer materials spun through the respective spinning nozzles 131 and 132 is wound around a roller (not shown).

  Next, the electric heater unit 140 according to the present invention has a structure surrounding the spin block unit 120 and serves to apply heat to the spin block unit 120. At this time, heat higher than the melting temperature (melting point) of the polymer raw material to be input is generated. For example, heat of 50 to 350 ° C. can be generated and applied to the spin block unit 120.

  As a result, when high-temperature heat is applied to the spin block 120, the polymer raw material melted and transferred by the extruder 110 is kept constant at a uniform temperature equal to or higher than the melting temperature. It can be transferred in the state.

  The electric heater unit 140 of the present invention is different from the existing heater method in which heat is applied using a toxic substance, and has a characteristic of applying electric heat, which not only improves the thermal efficiency at high temperatures but also is toxic. It can also ensure the safety of workers who work in the environment of materials.

  However, although it has been described that only the electric heater system is applied according to the first embodiment, the present invention is not necessarily limited to this, and it is needless to say that an existing system can be applied depending on circumstances.

  Next, the cooling device unit 150 of the present invention is formed at the lower end of the spinning nozzle unit 130, and applies either air cooling or water cooling depending on the thickness of the fiber yarn 170 spun from the spinning nozzle unit 130. Constructs a cooling device. The cooling device 150 serves to cool the fiber yarn spun in a state of being extruded from the spinning nozzle unit 130 at a high temperature and high pressure with air or water.

  Here, when an air cooling type cooling device is applied, it is selectively employed when the thickness of the fiber yarn spun from the spinning nozzle unit 130 is 30 denier or less, and a water cooling type cooling device is applied. In this case, it is preferable that the fiber raw yarn spun from the spinning nozzle portion 130 is selectively employed when the thickness is 30 denier or more.

  Finally, the height adjusting unit 160 of the present invention has an elevator-like structure that is fixed to both side surfaces of the spin block unit 120 and can move up and down. The height adjusting unit 160 integrates the above-described extrusion unit 110, the spin block unit 120, and the spinning nozzle unit 130 so that each cooling device unit 150 is formed at the lower end of the spinning nozzle unit 130. Or it can be used to adjust the height individually.

  For example, when a water-cooling type cooling device is formed at the lower end of the spinning nozzle unit 130, the water-cooling type cooling device is formed at the lower end of the spin block unit 120 to which the water-cooling type cooling device is fixed. In order to achieve this, it is inevitable to adjust the height of the extrusion unit 110, the spin block unit 120, and the spinning nozzle unit 130. In this case, the height adjustment unit 160 is formed so that the heights of the extrusion unit 110, the spin block unit 120, and the spinning nozzle unit 130 can be adjusted. Thereby, in this 1st Example, both the cooling device of an air cooling system and a water cooling system can be installed.

  Next, the spin block part 40 of the present invention has a structure including a plurality of gear pumps 50 to 55 and a flow path pipe part 120 described later, and is manufactured from a metal alloy material, but is not necessarily limited thereto. If the material has high thermal conductivity, it can be replaced with another material.

  Next, the gear pumps 51 to 55 of the present invention have a structure in which a plurality of gear pumps are connected to each of the extruders 10, 20, 30, that is, the gear pumps 51, 52 formed on the right side inside the spin block unit 40 are spin block units. The gear pumps 53 and 54 that are connected to the extruder 10 and the corresponding flow pipe 60 formed on the right side of the outer side 40 and are formed on the upper side inside the spin block unit 40 are formed on the upper side outside the spin block unit 40.

With such a connection structure, the gear pumps 53 and 54 of the present invention serve to discharge the polymer raw material that has been melted and extruded from the extruders 10, 20, and 30 by the gear motor at the same or different discharge amount. It becomes like this. At this time, discharging different discharge amounts means discharging with different fiber thickness.

  Thus, in the second embodiment, in the existing melt spinning machine (or compound spinning machine), only one gear pump can be provided for each extruder with respect to one extruder or two extruders. In order to improve the limit, three or more extruders 30, 40, 50 are provided, and two gear pumps are included in each of the extruders 30, 40, 50.

  However, the present invention is not limited to the configuration of two gear pumps for each of the extruders 30, 40, 50 and the extruders. Although structurally unlikely, an extruder and a gear pump can be further provided. Needless to say.

  Next, the flow channel tube block part 210 of the present invention has a configuration showing a part of the spin block unit 40, and a flow channel tube unit 220 described later is accommodated inside the flow channel tube block unit 210 of the spin block unit 40. Has been. Such a channel tube block part 210 is preferably made of a metal alloy so as to improve the heat transfer efficiency, and needless to say, it can be replaced if it is a substance capable of heat transfer.

  Next, the flow path tube part 220 of the present invention has a structure comprising a plurality of flow path pipes individually formed in the spin block part 40 for each gear pump for each of the extruders 10, 20, and 30. Here, each flow channel pipe serves as a passage through which various molten polymer polymers supplied from the corresponding gear pumps 50, 51, 52, 53, 54, 55 pass. The structure of such a channel pipe part 120 will be described in more detail with reference to FIGS.

The structure is such that heat is applied to the channel tube block part 210 of the spin block part 220. At this time, since the channel tube block part 210 is made of a metal alloy, the polymer polymer is transferred in a hard state by transferring high-temperature heat to the polymer polymer inside the channel tube unit 220. Instead, it is maintained in a molten state and can be quickly transferred inside the channel tube portion 220.

  Next, the spinning nozzle unit 240 of the present invention can include a plurality of spinning nozzles, for example, two spinning nozzles 241 and 242, and a plurality of spinning nozzles 241 and 242 are connected to each other via an arbitrary flow path pipe.

  Therefore, since the spinning nozzle section 240 of the present invention can flow various types of molten polymer polymers into the respective spinning nozzles 241 and 242, simultaneous spinning is possible. Next, the fiber yarn 270 containing a large number of polymer materials spun from the respective spinning nozzles 241 and 242 is wound around a roller (not shown).

  The cooling device 70 of the present invention is formed at the lower end of the spinning nozzle portion 240, and the structure of the cooling device to which any one of the air cooling method and the water cooling method is applied depending on the thickness of the fiber yarn spun from the spinning nozzle portion 240. Make. Such a cooling device 70 serves to cool the fiber yarn spun in a state of being extruded from the spinning nozzle portion 240 at a high temperature and high pressure with air or air.

  For example, when the air-cooling type cooling device 70 is applied, it is selectively employed when the thickness of the fiber yarn spun from the spinning nozzle section 240 is 30 denier or less, and the water-cooling type cooling device 70 is used. In the case of application, it is preferably employed selectively when the thickness of the fiber yarn spun from the spinning nozzle section 240 is 30 denier or more.

  Next, the height adjusting unit 80 of the present invention is in the form of an elevator that is fixed to both side surfaces of the spin block unit 40 and can be moved up and down, and in the cooling device 70, the corresponding cooling device is the spinning nozzle unit 240. It functions to adjust the heights of the extruders 10, 20, 30, the spin block unit 40, and the spinning nozzle unit 240 so as to be formed at the lower end.

  For example, when the water-cooling type cooling device 70 is formed at the lower end of the spinning nozzle unit 240, the water-cooling type cooling device has a larger size than the air-cooling type cooling device and is formed at the lower end of the spin block unit 40 to which the water-cooling type cooling device is fixed. In order to achieve this, adjustment of the heights of the extruders 10, 20, 30, the spin block unit 40 and the spinning nozzle unit 240 is inevitable. In this case, the height adjusting unit 80 is formed so that the heights of the extruders 10, 20, 30, the spin block unit 40, and the spinning nozzle unit 240 can be adjusted. Thereby, in this 2nd Example, both the cooling device of an air cooling and a water cooling system can be installed.

  With such a structure, in the second embodiment, not only multi-component fibers (multi-component yarns) but also mixed fibers (mixed yarns) can be produced in various forms of fiber raw yarn 90. It is.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, in FIGS. 3 to 10, in the physical structure of the gear pump unit 120 </ b> A and the spinning nozzle unit 130 of the multi-fiber spinning device according to the first embodiment described above, the gear pump unit 120 </ b> A and / or spinning. The control method of the nozzle part 130 and the fiber yarn manufactured thereby will be described in more detail.

Example of Control Method of Multiple Fiber Spinning Apparatus FIG. 3 is a flowchart illustrating an example of a control method of the multiple fiber spinning apparatus 100 according to the first embodiment of the present invention.

  As shown in FIG. 3, the control method (S200) of the multi-fiber spinning device 100 according to the first embodiment of the present invention is an individual spinning nozzle connected to any one gear pump of a plurality of gear pumps 120A for each extruder 110. This is for controlling the plurality of gear pumps 120A and the plurality of spinning nozzles 130 so that various molten polymer polymers adjusted by the same or different discharge amounts for each of 131 or 132 can be fed and spun simultaneously.

  For this reason, the control method (S200) of the multi-fiber spinning device 100 according to the first embodiment of the present invention uses the same or different polymer melted and transferred from the extruder 110 for each of the plurality of gear pumps 120A by the extruder 110. The step of controlling the plurality of gear pumps 120A so as to discharge at different discharge amounts (S210); and any one of the plurality of gear pumps 120A for each of the extruders 110 so that various molten polymer polymers are charged and spun simultaneously. And controlling individual spinning nozzles 131 or 132 connected to the two gear pumps (S220).

  Therefore, as a result of controlling the plurality of gear pumps 120A and / or the spinning nozzle 130, at least one of the multiple composite fibers (multi composite yarn) and the mixed fiber (mixed yarn) can be manufactured individually or simultaneously. It can be done. Here, referring to FIGS. 4 and 7 for the production example of the multiplex composite fiber, and the production examples of the mixed fiber will be described in more detail with reference to FIGS.

Example of Multiple Composite Fibers FIG. 4 is a view exemplarily showing the structures of a gear pump 120A and a spinning nozzle 130 to be controlled to manufacture the multiple composite fibers according to the first embodiment of the present invention, and FIGS. It is a figure which shows illustartively the cross-sectional shape of the multi-component fiber 170 manufactured by FIG.

  4 shows a plurality of gear pumps 122, 123, 126 to be controlled in the gear pump section 120A of FIG. 1, a spinning nozzle 132, and flow passage tubes 122a, 123a, 126a formed therebetween. At this time, it is assumed that the illustrated plurality of gear pumps 122, 123, and 126 are examples, and discharge different polymer polymers.

  As a result, the control method of the multi-spinning apparatus 100 according to the present invention controls the three gear pumps 122, 123, 126 and / or one spinning nozzle 132 to thereby connect the spinning nozzles connected to the gear pumps 122, 123, 126. From 132, three kinds of high molecular polymers can be simultaneously spun in a fixed pattern.

  Thus, the multiple composite fiber (multi composite yarn) 170 in which three kinds of polymer materials are produced in a predetermined pattern can be shown as a result as shown in FIGS. First, the multiple conjugate fiber 170 shown in FIG. 5 shows an example of a core-sheath cross-sectional shape including three types of high polymer materials 171, 172, and 173, and the multiple conjugate fiber 170 shown in FIG. A sea-island type cross-sectional shape in which a large number of molecular polymer materials 171-1, 172-1, 173-1 are formed in a regular pattern is shown as an example.

  On the other hand, the multiplex composite fiber 170 shown in FIG. 7 shows, as an example, a split-type cross-sectional shape in which three types of high-molecular polymer materials 171-2, 172-2, and 173-2 are divided based on the center.

  Thus, as can be seen from FIG. 5 to FIG. 7, in this example, it was confirmed that multiple composite fibers of various forms can be manufactured by controlling one spinning nozzle connected to a plurality of gear pumps. . However, the present invention is not necessarily limited to this, and by simultaneously controlling the spinning nozzles connected to a plurality of gear pumps, multiple composite fibers of different forms can be produced for each spinning nozzle. Needless to say.

Example of Mixed Fiber FIG. 8 is a view showing, as an example, a gear pump 120A to be controlled and a spinning nozzle 130 for manufacturing the mixed fiber according to the first embodiment of the present invention, and FIGS. 9 and 10 are diagrams of FIG. 8 of the present invention. It is a figure which shows the cross-sectional shape of the mixed fiber 170 manufactured by the control result exemplarily.

  FIG. 8 shows a plurality of gear pumps 121, 122, 125, 126 and a plurality of spinning nozzles 131, 132 to be controlled in the gear pump unit 120A of FIG. 1 according to the first embodiment of the present invention, and a flow formed therebetween. The path pipes 121a, 122a, 125a, 126a are shown. At this time, it is assumed that the plurality of illustrated gear pumps 121, 122, 125, and 126 discharge different polymer polymer discharge amounts as an example.

  As a result, the control method of the multi-spinning apparatus 100 of the present invention controls the operation of the four gear pumps 121, 122, 125, 126 and / or the two spinning nozzles 131, 132, thereby causing the U1 and U5 gear pumps 121, Two types of fibers having different thicknesses can be simultaneously spun from the N1 spinning nozzle 131 connected to the 125, and 2 different in thickness from the N2 spinning nozzle 132 connected to the gear pumps 122 and 126 of the U2 and U6. The seed fibers 170A and 170B can be spun simultaneously.

  At this time, the fiber yarns spun from the respective spinning nozzles 131 and 132 are interlaced with each other in an irregular pattern by an interlacing nozzle 180 or an air-texturing nozzle 180 again. This makes it possible to manufacture a mixed fiber (mixed yarn) 170 in which 2 to 4 types of fiber materials having different thicknesses are mixed in an irregular pattern. Since the interlacing nozzle 180 and the air texture rising nozzle 180 are commonly used nozzles, detailed description thereof is omitted.

  An example of the mixed fiber 170 manufactured in this way can be shown in FIGS. The mixed fiber 170 shown in FIG. 9 shows a result of irregularly patterning and mixing four kinds of fiber materials 174, 175, 176, and 177 by two spinning nozzles and an interlacing nozzle or an air texture rising nozzle. The mixed fiber 170 shown in FIG. 10 includes a core-sheath type composite yarn having a circular cross section manufactured from two types of polymer materials 174-1 and 175-1 and the other two types of polymer materials 176-1 and 177-1. FIG. 10 shows the result of irregularly patterning and blending two types of composite fiber materials having a shape different from that shown in FIG.

  If both the N1 spinning nozzle 131 and the N2 spinning nozzle 132 shown in FIG. 8 are controlled, it is possible to produce an irregularly patterned mixed fiber 170 by simultaneously spinning a variety of, for example, four types of polymer polymers. Needless to say. Thus, controlling two spinning nozzles is more advantageous for producing blended fibers than for producing composite fibers. However, mixed fibers can be produced also when one spinning nozzle is controlled.
